# This Makefile is for Dropbear SSH Server and Client
# @[email protected]

# invocation:
# make PROGRAMS="dropbear dbclient scp" MULTI=1 STATIC=1 SCPPROGRESS=1
#
# to make a multiple-program statically linked binary "staticdropbearmulti".
# This example will include dropbear, scp, dropbearkey, dropbearconvert, and
# dbclient functionality, and includes the progress-bar functionality in scp.
# Hopefully that seems intuitive.
